Keratin is a component of the protein, but differs from it in that it contains a large amount of sulfur. It swells very well in water, has a rather low specific gravity and is highly soluble not only in alkalis, but also in sodium and potassium solutions. In the process of decomposition, like other proteins, it decomposes into ammonia, fatty acids, tyrosines, hydrogen sulfide and leucines.
What is keratin
This is a fairly strong protein and a very important component in human skin. It plays an important role for hair, nails of teeth (and also for hoofs and horns of animals). Its structure contains amino acids, which have very useful properties. In a wide variety of compounds, such a substance can be either very soft (for example, skin) or very hard (animal hooves). Keratin for hair is extremely important. It is based on dead cells. They perfectly protect that gentle layer, which is just beginning to form.
Keratin production
This substance has cysteine disulfide, which allows you to create bisulfide bridges. Such chains look like a spiral structure, which is very stable, because sulfur atoms in a spiral are very close to each other. Thus, a fibrous matrix is obtained in which the degree of solubility is very high. Such a connection is quite strong and flexible.
That is why keratin for hair is quite important. It contains a lot of sulfur, which in the combustion process forms a persistent unpleasant odor. A similar substance is formed by certain living cells (keratinocytes) that synthesize it. They serve as the basis for hair, nails and skin. These cells always go up, and after they die, they begin to form a kind of protection. Keratin can be damaged during psoriasis. At this time, a peeling process appears.
What does keratin mean for hair and nails?
Over time, nails and hair begin to become dry and brittle. When keratin cells die, this process is significantly accelerated. A similar phenomenon can be stopped if you eat gelatin and regularly moisturize your hair. Liquid keratin for hair is perfect for these purposes. With it, the curls will acquire shine and will look well-groomed and neat. The larger the layer of such a substance, the healthier will be the hair and nails. Extra hydration will help keep them healthy and protect against damage.
Keratin mask at home
A hair mask with keratin, prepared independently, will help to save a lot. To create it, you will need lemon juice, aloe juice, a few drops of rosemary oil. All components must be mixed and applied to clean, dry hair. Wait 10 minutes and rinse the hair well. For drying, do not use a hairdryer, it is better to just use a towel.
Thus, we see that keratin for hair and nails is very important, you can ensure their healthy appearance and beauty with proper care.
